Fig. 2 is a vertical sectional View on line 2-2 of Fig. 1,.

Fig. 3 is a fragmentary' perspective view ofthe invention showing one of the paint applying elements.

Fig. 4 is a fragmentary perspective view showing the gear shifting link mounted on the inner side of the frame.

Fig. 5 is a perspective view of one of the guide blocks shown partly broken away.

Fig. 6 is a vertical view of a part of one of the paint applying rollers.

Fig. 7 is a perspective view of an embossed auto tag.

Fig. 8 is a sectional view on line 8-8 of Fig. 7 and Fig. 9 is a perspective view of the oscillating roller support and its bracket, the roller not being shown, and Fig. 10 1s a perspective view of the roller members alone.

In the drawings, A represents. the main frame of the machine consisting of side members 1 and 2 suitably joined together by means of tie rods 3 at the base of the frame, and comparatively wide horizontally disposed Hat tie members 4 at the top of said side members.

.The side memfbers -1 and 2 are formed wlth a horizontally disposed straight upper edge 5 flush with the feed table 6 and delivery table 7 at opposite ends of said side `member, said table being mounted on the respective tie members 4; at 'what may be termed as the receiving end of the machine.

rFhe side members are formed with upwardly extending rectangular comparatively wide supporting lugs 8 arranged laterally in alinement one on each side member.

Spaced at regular sucessive intervals from the lug 8 and extending likewise from the edge 5 on each of the side members are a pair of similarly constructed paint roller housings B and C, the housings on one side of the frame being in exact lateral alinement wlth the corresponding housings on the opposite side thereof. v

The housings B and C and the lugs 8 are preferably integral with their respective side members, each of the latter being provlded with an outwardly extending lug 9 at the upper edge thereof, said lug being threaded to receive a vertically disposed set screw 10.

Fitting flatly against the inner surface of,

each ofV said supporting lugs 8 so as to slide thereon' and extending upwardly and beyond the latter and having screw threaded connection with the set screws 1l in the vertical disposed slots 12 in the supporting lugs 8 are the vertically movable housings D.

Each of said housings is formed with an outwardly extending lug 13 located directly over the lug 9 so as to rest upon the end of the set screws 10 in the latter, whereby the housing may be moved in a vertical plane and heldpositioned on the frame A by the set screws 11.

Rotatably mounted in each pair of the housings B, C and D isa paint applying soA roller 14:.. The rollers 14 are -comparatively l large in diameter, each roller being mounted on a shaft 15 reduced at its respectivel ends to form journals 16 adapted to run in journal boxes 17, which in turn are adapted to slide in runways 18, each journal box abutting again-st a coil spring 19 in the bottom` of its respective runway. Thus, each roller together with its shaft and journal boxes is rendered bodily movable in the l housing for the purpose of adjusting the positions relative to its \of the roller is provided, the spindle having threaded connection in the`housing at the opposite end of its respective runway and belng provided with ,a suitable hand wheel and a lock nut 22. The spindle abuts against the journal box opposite the spring 19 so that when the screw is turned the box may be slid in the runway as desired.

The enlar ed rtion of the shaft 15 is screw threa ed t roughoutr the major portion of its length, the thread being a square thread whih snugly fits the bore of the roller 14, a pair of lock nuts 22 one on each side .of the latter serving to hold the roller positioned thereon.

In the drawings are shown auxiliary paint applying rollers 23` one on either side of the roller 14 whereby border lines and the like on the auto tag may be separately coated. Anynumber of auxiliary rollers may be used as desired, the paint carrying rollers 63 and 64 being made long enou h to cover additional roller as indicated inv otted lines in Fig. 2.

The paint applying rollers are surfaced peripherally with an elastic oom sition jacket 24 composed of elastic material such as is commonly used on inking rollers of printing presses. As indicated in Fig. 6 the elastic jacket surrounding the roller 14 extends across its full width while the auxiliary rollers are provided with side fianges 25 to support the elastic material on the periphery thereof. A

As shown in Fig. 1 of the drawings the runways 18 in the housings B and C are disposed vertically while that in the housingI D is disposed horizontally, the object lof which will be hereinafter explained;

' The shafts 15 in the housings B kand C respectively extend at one of their ends through and beyond their respective journal boxes and carry rigidly on said extending end a spur gear 26, the pitch circle thereof bein approximately equal to the diameter oft e composition jacket of the paint ap pl ing rollers.-

he shaft 15 in the housing D and the shaft 27 have journals 28 in the side members ofthe frame A and are parallel with the first named shaft the latter carrying rigidly the gears 29, said-gears being located adjacent the inner faces of one of the housings D one above the other. The diameter of the gears 29 corresponds to that of the gears 26 'was does valso the gear 30 rigidly 'mounted on the extending end of the shaft 27.

Corresponding to the shaft 27 and located in the Same horizontal plane therewith and beneath each ofthe shafts 15 in the housings `actly similar to the spur gear 30 an B and Cl respectivelyare the shafts 31 also i journaled in the side members in the frame and carrying rigidly on one of their outer ends the spur gears 32, the latter bein ex- 26, each of the spur gears 32 meshing withi'ts respective gear 26 in the housings B and C.

Botatably mounted on studs 33 and projecting outwardly from the outer `side of the side member of the frame A are the spur idlers 35 rotatably Supported on the studs 36 also projecting outwardly from the side member 2 of the frame.

f As shown in Fig. l of the drawings the gears 34 mesh with the gear 30 and the gears 32 so as to form ahorizontally disposed ear train on the outside of the frame It will be noted that the pitch circles of the gears 27 and 32 and the gears 29 meet in the horizontal plane corresponding to the plane in which lies the faces of the tables 6 and7.

Rigidly mounted on the shaft 27 l and shafts 31. and of a diameter equal to the diameter of the rollers 14 are the comparatively long rollers 34', said rollers being made of extended length to permit the use of paint applying rollers of various lengths. The rollers 34 are centrally disposed between the side members of the frame and normally roll on the surface of the paint applyingrollers 14, so that when an auto tag is inserted between them and the rollers are turned the composition jacket of the rolle'rs 14 will grip the embossed surface of the tag, the soft surface of the composition yielding to the irregular height of the embossed portions of the tag v.(as indicated in dotted lines in Fig. 8) so that the paint maybe applied to all the embossed surfaces irrespective of their height. The mechanism supported on each of the housings B, C and D together with the roller 34 constitutes a complete paint applying device or unit, the three --units bein operatively connected by the gear train. he paint applying mechan ism su ported on the housing D may be termed t e initial paint applying device.

Parallel with the shafts 15 and 31 and also rotatably mounted at their ends in the numbers 1 and 2 ofthe frame and being of that of the rollers 34 and the carrier rollers gears 34 arranged to mesh/with the uniform diameter and of a: length equal to 37 mountedon shafts 38, the latterprojecting through' and beyond the side memberv2` and carrylng on saidextended end the spur gears 39.

As shown in Fig. 1 there are nine carrying rollers eight thereof being `arranged 1n palrs, one pair meshing four gears 34 and the ninth thereof meshing with the gear 34 adjacent the receiving table 7.

with/each of the 'i ,s mesh if the tinuous travel an auto tag of ,ordinary s explained in the foregoing, the housings D may be raised or lowered by means of set screws so as to carry the mechalen 0 nism supported thereon bodily with it. 0b-

viously, the ears 29 would be moved Out of ousings were raised any considerable distance. To obviate disconnec- `tion of the gears applicant has provided '5 mechanism (shown in'Figs. 1 and 4) rotatably mounted on the frame by means of the stud :,.,1.40 and adapted to swing in a vertical plane,

a link 41 havin pivotal connection 42 with l the link 43 which in turn has pivotal con- Oqnection 44 with the housing D, the latter being mounted on the side member 2 of the `rame.. The link 41 is provided with an arcuate slot 45 arranged concentric kwith the pivot 40 and adapted to receive a set screw 46 5 screw threaded in the side member 2 of the frame so that the link 41 may be swung around its pivot to any desired degree and then set against movement by meansof the set screw. On the pivot pins '42 and 44 are rotatably mounted so as to mesh with each other the gears 48 and47 respectively, the gear 1 47 meshing in turn with the upper gear 29 on the shaft 15. Thus, the housing D may be 'raised to any desired distance without oper- 5 atively disconnecting the mechanism car- 0 thelgear 34 on the shaft 27.

' By means of the belt pulley 49 (Fig. 3) rigidly mounted on one ofthe shafts 38 the gear trainmay be driven yfrom any suitable *power source to actuate the paint applying 5 rollers 14. ln Fig. v3 is'shown a perspective j view of the housingB which is an exact lduplicate of the housing C.

Rotatablyimounted in the upper ,portionof the housing is the roller 50, the shaft 51 J thereof being journaled in the journal block fand adjusted by an adj'usting screw similar tto the rollers 14 hereinbefore described.

ab Contacting with the roller and similarly mounted in the housing is the roller 52, S the periphery of' the Nlatter depending into a paint receptacle" 53 supported on a transverse bar A54-sec1'1'red to the housing. rlhe receptacle or pan 53 is removably supported on the 'bar 54 by means of an angle member 5{5- havin-g slots` 56 arranged longitudinally with the barA to receive"set screws 57 whereby the angular member may be slidably held, a spring .member 58 urging said angular member constantly in a lateral direction to press the pan against an oppqsitely disposed an lar member 59 secured I on the bar- 54. ach angular member is provided with a yoke 60 adapted to embrace the end of the pan to effectively grip' the latter. Thus, when it is desired to raise the roller 14 to accommodate auto tags of various thicknesses the adjustment screws 20 may be suitably adjusted to keep the rollers 50 and 52 and 14 in contacting relation.

The shafts y51 and 52 extend through and beyond the housing B and carry at their outer ends the gears 61 and 62 meshing with each other, thegear 62 in turn meshing with the ,gear 26 on the shaft 15. Thus, when the gear .train is actuated the paint carrying rollers 50 and 52 are positively driven.

Between the housings D above the roller 14 are rotatably mounted the paint carrier rollers 63, 64, 65, 66 and 67, the rollers 63, 64 and 67 being mounted in the' housings after the manner hereinbefore described in connection with the rollers 14, it being thought not necessary to further describe being vconstantly in contact with each other peripherally may be bodily moved in the runway 70. adapted to roll peripherally on the roller 14, but they may be adjusted if desired to be slightly separated therefrom as can also the roller 67 with respect to roller 66 and in turn have peripheral Contact with the roller 65. The rollers 50 and 52 can also be adjusted so as to leave a small space between them andbetween the rollers 50 and 14 so that the paint will be transferred by capillary attraction. A paint receptacle or pan 73 constructed von similar lines to pan 53 hereinbefore described, receives the lower portion of the roller 67 whereby the paint in the pan is carried to the roller 66 from whence in turn it is transferred to the roller then to the rollers 63 and 64 and nally to the paint applying roller 14 which in turn contacts with the article to be painted. Each of the rollers 63, 64, 65, 66 and 67 carry on their respective shafts at a point adjacent t'he housing D on side member 2 a gear wheel indicated by the numerals 63, 64, 65, 66 andv .67 in order to identify them withv their re- The rollers 63 and 64 are 45o at the top of the movable clocks E adapted vto permit' the' latter to reciprocate laterally for the purpose of distributing the paint as 1 of the frame and extending outwardly therefrom is the bracket 74, the latter rosurrounding the outer edge Uhereof.

tatably supporting a pivot member 75 adapted, to rotate in a transverse vertical plane with respect to the machine and hav-'1 ing a stud 76 perpendicular to its axis of rotation, said stud ,forming a journal for the rollers 77 and 78. One the shaft 79 of the roller 65 is a grooved circular cam 80,' the groove 81-thereof being rectangular in cross section and adapted to receive the rollers 7 7 and 78, the latter'tting snugly into said groove and being adapted to roll onthe side walls thereof.v The circular cam is mounted on the shaft 79 so that the axis of rotation of the shaft 79 is at an angle with a perpendicular erected oincident with the center of said circular cam. Thus, when the shaft groove 81 and rotatepa-rtly around the axis of rotation of the pivot member 75 causing the shaft 79 to reciprocate. the gear train will disclose that when the pulley 49 is driven tothe right the rollers 34 and the rolls 39 will travel in feeding direction while the rollers 14 will travel in opposite direction, the gears and'rollers being so proportioned as to secure the same 'peripheral velocity in all the rollers and rol s.

In Fig. 7 is shown an ordinary auto tag 82 formed with Aan embossedbead 83 complertlellly e numerals are not embossed. as deeply as the bead as is plainly indicated in Fig. 8 it therefore requiring ,a comparatively soft compositioncoating on the rollers 14 to effectively distribute bossed surfaces. i

In the machine illustrated in the drawings the tagvis fed lengthwise into the machine from the table 6 between the rollers the paint on the emn 14 and the rollers'34; it isthencarried forward frictionally, vit 'being guarded by the spaced spring blades or fingers 84 secured to be clamped on the transverse rods 85 extending from one side member to the other of the frame. The; rods are shown square in cross section and it loosely into a notch in the lower portion 86 of the block 8, the

upper `portion 87 thereof being adapted to be clamped over saidrod by means of the screws 88 piercing the block 87 and'having screw threaded connection withv the block 86. The spring blades 84 are arranged in the path of the traveling tag and engage under stress the passing tag as' it is carried forward by the rollers 37 from one paint Inspection of applying roller to the other. .In operation the pans 73, 53 and the 'pan suspended in the housing C, are each supplied with a quantity of paint, which latter may be ordinary I surface of the paint applying roll of eachv unit may be cut away in places, if desired,

so that a second or third coat, as the case may be, will be applied to certain parts only,

of the tag. It is'also to bev understood that the paint may be mixed inthe ordinary way to render it suitable for first, second and c third coat purpose, it beingl common knowl- -edge in the palnters art to add or mix certain ingredients for subsequent coats, such, for example, as linseedeoil or japan drier. By judiciously using the adjustment screws 20 Afor the various f'rollers the pressure.-l

broughtrto bear on the auto tag .may be varied as required, the springs under each of the journal boxes urging'the rollers constantly in an upwardly direction away from the pass tag.
